Abstract:

This thesis is concerned with the life and career of Sir Philip Baxter (1905-1989), particularly during the period following his arrival in Australia from England in 1950. But the thesis is not a conventional biographical study in terms of either the sources used or its guiding themes. Instead, my subject's values and attitudes are portrayed as reflections of a 'conservative style of thought', a concept developed by Karl Mannheim. This approach, centred on close readings of key texts, permits a deeper understanding of a figure who polarised opinion over a long career as Chairman of the Austral

L'ampio utilizzo di nanomateriali ingegnerizzati (ENM) in svariati prodotti sta suscitando una crescente attenzione sull potenziale rischio di ENM nei confronti della salute umana e l'ambiente. Nonostante le indagini tossicologiche fin qui condotte, solo in poche di esse è stata condotta la caratterizzazione di ENM prima, durante e dopo i test tossicologici. In questa tesi, all’interno del progetto europeo EU-FP7 (ENPRA) e nazionale (PRIN 2009), è stata effettuata una caratterizzazione completa di alcuni più diffusi ENM (i.e. n-TiO2, n-ZnO, n-Ag e MWCNT).

This thesis is focused on understanding the fundamental physical interaction occurring, when a material interacts with a biological fluid containing protein molecules and cells. The interaction of proteins with defined surface chemistry and nanotopography is of major interest in the field of biomaterials. Despite the degree of research undertaken to study this interface, there is still a lack of understanding of how the protein layer evolves with respect to surface parameters, and further how cells condition the surface. By understanding these processes, advanced biomaterial coatings may be de

Methylxanthines are natural and synthetic compounds found in many foods, drinks, pharmaceuticals, and cosmetics.

Abstract:

The need for improving the efficiency and reducing emissions is a constant challenge in combustion engine design. For spark ignition engines, these challenges have been targeted in the past decade or so, through ‘engine downsizing’ which refers to a reduction in engine displacement accompanied by turbocharging. Besides the benefits of this, it is expected to aggravate the already serious issue of engine knock owing to increased cylinder pressure. Engine knock which is a consequence of an abnormal mode of combustion in SI engines, is a performance limiting phenomenon and potentially damaging to

Abstract:

Engineered protein nanopores can be used to investigate a wide range of dynamic processes in real time and at the single-molecule level, for example covalent bond making and breaking or the interaction of ligands with their cognate binding sites. The detection of such processes is accomplished by monitoring the current carried by ions through the pore in an applied potential, which is modulated as molecules of interest interact with engineered binding sites within the pore. In contrast to ensemble measurements, where the behaviour of individual molecules is obscured by averaging, single-channe

Abstract:

The objectives of this research were to investigate the heat resistant performance of a structural adhesive and to analyze the contribution of the adhesive to the chemical emissions from the glued wood products affected by the elevated temperatures. Phenol-resorcinol-formaldehyde (PRF) and two wood species, southern pine (Pinus palustris) and Douglas-fir (Pseudotsuga menziesii), were investigated. The dynamic mechanical analysis (DMA) test results showed that the heat durability performance of cured PRF resin was better than that of the two wood species used in this study. The results indicate

Abstract:

The formation of embryoid bodies has long been utilized to initiate differentiation of embryonic stem cells in vitro. The embryoid body provides an effective means of recapitulating early stages during embryogenesis and formation of the three germ layers. Current methodology for embryoid formation is extensive but exhibits a lack of standardisation and coherence. Here is shown a 3D culure system for controlled embryonic stem cell aggregation via a non-cytotoxic cell surface modification and cell-cell cross-linking. Embryoid body formation was found to be a complex relationship between embryoni

Abstract:

Compatibility of fuel delivery materials (FDM) with biodiesel fuel in the fuel delivery system (FDS) under real-life common rail diesel engine (CRDE) operation poses a challenge to researchers and engine manufacturers alike. Although standard methods such as ASTM G31 and ASTM D471 for metals and elastomers, respectively, are deemed suitable for evaluating the effects of water content, total acid number (TAN) and oxidation products in biodiesel on FDM degradation, they do not resemble the actual engine operation conditions such as varying fuel pressure/temperature as well as the presence of a w
